Using the QtJambi generator for Qt-based libraries? (e.g. KDE frameworks)

[sowelipililimute]

A cursory attempt:

../6.6.0/build/linux-x64/qtjambi/bin/QtJambiGenerator /home/jblackquill/KDE/usr/include/KF6/KConfigCore/kconfigbase.h

results in a

************************************************************************
Not in type system
 - KConfigBase     /home/jblackquill/KDE/usr/include/KF6/KConfigCore/kconfigbase.h
************************************************************************

Some further prodding, I need a typesystem file:

import QtJambiGenerator 1.0

TypeSystem{
    packageName: "org.kde.kf.kconfig"
    qtLibrary: "KConfig"
    module: "kdejambi.kconfig"
    description: "KConfig java bindings"

    ObjectType{
        name: "KConfigBase"
    }
    ObjectType{
        name: "KConfig"
    }
}

and an all.h

#include "/home/jblackquill/KDE/usr/include/KF6/KConfigCore/kconfigbase.h"
#include "/home/jblackquill/KDE/usr/include/KF6/KConfigCore/kconfig.h"

and

../6.6.0/build/linux-x64/qtjambi/bin/QtJambiGenerator -t KConfig.qml all.h

Doesn't seem to be generating KConfig's class, but is generating KConfigBase.

This pattern persists if I attempt to add more classes.

Add include directory with -I /home/jblackquill/KDE/usr/include/KF6 and then only add #include <KConfigCore/kconfig.h> to all.h. kconfigbase.h is included from there.

Also it is necessary to add the lication of Qt headers with -I because KDE uses these types. Then, you need to load QtCore typesystem (all Qt modules used by KConfig). Put the following in your typesystem (e.g. after description):

LoadTypeSystem{name: "QtCore"}

Generator produces some logfiles:

• reported_warnings.log
• mjb_rejected_classes.log
  etc.
  Can you show me the files?

Generator will warn you to specify ownership of parameter and returned result of KConfig::copyOf. Also, I recommend to reject the method virtual_hook, as it is not really useful in Java.

Furthermore, you will see that several methods lead to the same Java API and thus need to be sorted out. Example:
KConfigBase::group has const char* parameter and QString both mapping to java.lang.String. Also both, a const and non-const method same name and arguments lead to same Java API. You need to disable one of them.

Some enums have entries with the same numerical value. In this case, you need to make a manual selection by specifying RejectEnumValue.

In genera, I sugggest to look into existing typesystem specifications of QtJambi to see how to do all these things. If you have questions just post here.
